A theory of passive vitalism. Contemporary theory has pushed the boundaries of the concept of the living, urging us to consider a vitality that manifests beyond the human, animal, or even the organic altogether. Recognizing the vast variety of modes of existence and vibrancy entails—such is the claim—a new ethics and politics. In Inorganic Life, the philosopher Eckardt Lindner intervenes in this discussion. He claims that we have not yet properly understood how and to what effect we can break the organo-centrism of philosophy and have neglected to consider the inner contradictions of such novel amalgams of vitalism and materialism. As an unlikely ally in his critical project, he investigates the inner tension in Deleuze’s works between an overtly vitalist stance and critiques of classical forms of vitalism, bordering on a novel anti-vitalism. Against active forms of vitalism, interested in more immersion in the world, interconnectedness, and ever more efficacious praxis, one can find in Deleuze a passive vitalism. This subterranean thought in the philosophy of immanence highlights the capacity of life to disorient itself, to be out of line with itself, to detach itself from purposeful action and its own inner goals. Lindner explores this passive vitalism by drawing together thinkers such as Deleuze, Cioran, Laruelle, Kant, and Derrida. Suspicious of the moralistic and enthusiastic tendency of new materialisms, this vitalism would be inherently critical—even of its own commitments to liveliness—and thus gestures to a new politics and ethics of life.
